Common display problems

  • White lines running down the screen

  • Multicolored lines on the screen 

Solution: this laptop screen problem, again, may be caused by a faulty signal cable.

To see if this is indeed the case, you'll need to remove and inspect the back of your laptop screen. Our FREE video tutorial will help guide you through this process. If neither of these solutions work, this screen problem may be caused by a logic board fault. If this is indeed the case, you'll need to purchase a replacement screen
